Attackers face a ripple of rising compute costs across every duplicate identity, since each new key needs fresh work. A falcon-style verifier checks the puzzle chain, and a cedar-seeded randomness beacon prevents precomputation, so forging thousands of sybils costs far more than honest participation.
